erforming Guided
Setups and
Calibra-
tions
This
chapter shows
you
how
to
perform
guided
setups
,
guided
calibrations
,
and
manual calibrations
.
Calibrating
the
precision
reectometer
consists
of
balancing the
receiver
and
then
calibrating
the
magnitude
.
These
two
procedures
ensure maximum
accuracy
for
your
measurements
.
They
remove
DC
osets and
polarization
sensitivity
.
They
also
set
a
calibrated
reference
level.
Guided
setups
not
only
calibrate
the
instrument,
but
they
also
select
the
source
and
display
instructions
for
both
pigtailed
and
non-pigtailed
devices
.
Manually calibrating
the
instrument
is
generally
faster
that
using
the
guided
calibration.
When the instrument is calibrated, the status indicator
C
appears on the display's left-hand side.
